AT 80 Series Installation Instructions

Handling:
Unpack all dampers carefully. Immediately note any damage (bent hardware, kinked or torn side seals, missing screws, bearings, etc.) and inform your
representative. Do not install, especially if side seal may have to be replaced. It is easier to repair a damper on the floor than in ducting. Do not pile dampers on
each other or allow debris to fall on them. Avoid re-handling if possible; install each unit as soon as possible after unpacking.
Identification:
All dampers contain labels on which tagging, if called for, is included. Each section of multiple section dampers have labels which states its location in relation
to the other sections. It is very important that assembly should follow these labels to ensure that joining tabs fit and the "U" bolt connectors (where supplied) go
into matching holes supplied.
Installation:
1. Check the location of intended installation for any obstructions or
irregularities, which might interfere with damper operation. The duct
opening should measure a +1/4" over the damper dimensions, and
should be straight, square, level, and/or plumb. In horizontal duct
runs ('vertical' damper installation) ensure the area under the damper
is supported, to prevent sagging due to its weight.
2. Determine the location of the shaft extension (hole) before securing
the damper in place. Attach the spring clip mounted shaft extension
through the holes in the sleeve and bracket, to a 'power blade'. In a
parallel blade damper, all blades are power blades. In an opposed
blade damper, every other blade from the 'primary' blade are power
blades.
3. On dampers with blade and jamb seals, apply a bead of caulk around
the perimeter of the damper/sleeve joint on both sides of the damper
to prevent leakage.
4. Before concluding the installation, cycle the damper several times to
ensure unimpeded function.
5. For multi-section damper installations larger than 120" x 120",
mullions are recommended. Request pages F-57 and F-58 of Aire
Technologies' Installation Instructions package for details on
construction of and installations employing mullions. Alternatively,
consult the SMACNA Fire, Smoke, & Radiation Damper Installation
Guide on that subject.
6. Aire Technologies Air Control Dampers may be actuated with electric
or pneumatic actuators. Please consult the Installation Instructions
provided with those products for proper attachment of those items.
NOTE:
The bottom of the duct or wall opening must support the weight of the damper. The bottom of the duct must be a flat, square surface. If not flat, use shims to
keep damper bottoms in alignment. On larger multi-section installations, use adequate support and bracing to provide a rigid installation.
Improperly installed dampers and damper sections prevent the blades from sealing properly. Gaps between the blades and frame indicate a damper that is
installed out of square. Gaps between the blades indicate a damper installed out of flat. Gaps between the blades and jambs indicate a damper of square.

INSTALLATION INSTRUCTIONS
Series 80 Air Control Damper
WARNING:
1502 Industrial Drive, Monongahela, PA 15063
Operation Check:
A. Lubricate linkage, bearings, and other movable parts with a silicone
lubricant. Do not use petroleum-based products as they could cause
excessive dust collection.
B. Manual dampers should run through a full-open to full-close cycle by
hand to determine the good condition of the damper. If there is any
binding, it is up to the installer to:
a. Clean damper of any debris (dust, dirt, concrete, etc.) that can
obviously impede movement.
b. Check for straightness and twist.
c. Check side seals (if included) for kinks and tears.
d. Check for missing bearings.
e. Check that all hardware is undamaged and freely moving.
C. Motorized dampers should be checked by a preliminary attempt to
operate with the motor. If binding occurs, disconnect one end of the
driving linkage (and note its exact position beforehand) to operate
damper manually and check per above. Reconnect linkage and
check again. Obviously, if the motor is inoperative, this will become
apparent at first step.
Maintenance:
Once every 6 months, we recommend the following:
•
Tighten any screws that are loose.
•
Spray all moving parts with a silicone lubricant.
•
Clean and wipe down damper
